ULTRA-E-F
APPENDIX 2 ENERGY FUNCTION INSTRUCTION
1.
Introduction
Series ULTRA-E-FB&C flow meter owns an in-built module for energy calculation. It can
calculate the thermal enthalpy of the liquid of a certain temperature automatically. Accordingly
we can calculate the heat flow and totalizer. Temperature signal is input by analog hardware
T1, T2 which can only receive Pt1000 resistance signal.
2.
Wires Connection
Analog input can be connected to four temperature signals from outside. When calculating
energy, T1 connects to inlet sensor and T2 to outlet sensor.
Menu 06 displays the corresponding temperature.
3.
Energy Calculation
Energy = Flow× (thermal enthalpy at T1 temp. - thermal enthalpy at T2 temp.). This thermal
enthalpy is automatically calculated by heat meter according to international standard.
